Product Description

The Mitsubishi AY51 is a 32-point transistor output module designed for the MELSEC A Series programmable logic controllers (PLCs). It features a triac sink configuration, operating within a 12–24 V DC load voltage range. Each output point can handle up to 0.5 A, making it suitable for controlling various industrial devices such as solenoids and relays. The module utilizes photocoupler isolation for enhanced noise immunity and is equipped with LED indicators for each output point, providing clear status feedback. Its compact design and reliable performance make it an ideal choice for expanding the I/O capabilities of MELSEC A Series PLC systems.​
